I want to contribute code

Before opening a PR, please confirm that your changes must be contained in the firmware. Many ideas can easily be implemented as external applications and published in the Flipper Application Catalog (coming soon). If you are unsure, reach out to Flipper on the or the page, and they'll help you find the right place for your code.

Development

Flipper Zero Firmware is written in C, with some bits and pieces written in C++ and armv7m assembly languages. An intermediate level of C knowledge is recommended for comfortable programming. C, C++, and armv7m assembly languages are supported for Flipper applications.

Requirements

Supported development platforms:

  • Windows 10+ with PowerShell and Git (x86_64)

  • macOS 12+ with Command Line tools (x86_64, arm64)

  • Ubuntu 20.04+ with build-essential and Git (x86_64)

Supported in-circuit debuggers (optional but highly recommended):

  • ST-Link

  • J-Link

Flipper Build System will take care of all the other dependencies.

Cloning source code

Make sure you have enough space and clone the source code:

git clone --recursive https://github.com/flipperdevices/flipperzero-firmware.git

Building

Build firmware using Flipper Build Tool:

./fbt

Flashing firmware using an in-circuit debugger

Connect your in-circuit debugger to your Flipper and flash firmware using Flipper Build Tool:

./fbt flash

Flashing firmware using USB

Make sure your Flipper is on, and your firmware is functioning. Connect your Flipper with a USB cable and flash firmware using Flipper Build Tool:

./fbt flash_usb
